摘要： PURPOSE:To perform membrane separation action of high permeation flow and separation efficiency with small pressure difference by admitting the liquid to be treated from the hollow cylindrical part of a cylindrical hollow fiber layer which is packed with selective permeability hollow fibers at specific densities. CONSTITUTION:A cylindrical assembly 2 which is intersectionally disposed with hollow fibers of cellulose acetate, aromatic polyamide, etc. of 10-1,000mu in outside diameter and 3-80% in percentage of hollowness having selective permeability characteristics at 45-70% filling rate is supported by means of resin walls 3, 4 at both ends and a stanchion 20 and is put into a case 1. A cavity part 7 is axially provided at the center of the assembly 2, and one end thereof is connected to the conduit 11 penetrating in the resin wall 4 and the end plate 6 of the case 1. The hollow fibers are set in a U shape and both ends thereof are extruded to the outside of the assembly 2 through the resin wall 3. The water to be treated such as salt water is admitted through the conduit 11, and is pressure-fed into the hollow fiber layer 2 uniformly. The water permeates through the hollow fiber walls and is taken out from an outlet 9. The liquid concd. of other contents passes among the fiber layers and is discharged from an outlet 12 through the annular flow passage on the outer side.

摘要： PURPOSE:To simplify pipings, and make possible the miniaturization of the device and the arranging by placing in rows or stacking by so constituting the permeating fluid tank-out pipe as to pass through the inside of the flow cylinder member of the reverse osmosis device. CONSTITUTION:In a titled device constituted by disposing the elements 4 formed with multiple hollow yarns 5 into a bundle shape in single or plural rows within a pressure vessel (shell) 1, it is so constituted that a permeating fluid take-out pipe 14 penetrates through the center of the element 4 (fitting the opening side of the hollow yarn 5 to the fitting ring 13 of the pipe 14 and connecting the pipe 7 and the device) and is supported to cover plates 2, 3 through both side flanges 6, 7. Since said pipe 7 and concentrated water take-out pipe 10 are not mounted to the barrel part of the shell 1 as in the prior art, the pipings of conventinoal method may be simplified and the stacking of the devices is easy. This device is suited for desalting of sea water and production of pure water.
